Whey protein is the liquid byproduct of cheesemaking, but whey protein isolate is an even more refined version derived from it. This purification process removes the vast majority of non-protein components, leaving behind a supplement that is exceptionally high in pure protein.

Pasteurization, a standard part of modern dairy production, heats milk and its byproducts like whey to high temperatures, effectively eliminating most living organisms. This raises a critical question for health-conscious consumers: does whey have good bacteria, or are these beneficial microbes destroyed during the manufacturing process that turns milk liquid into a dry powder?

Originally, the liquid whey produced during cheesemaking was considered a waste product and often discarded. Now a global industry, whey protein comes from cow's milk and undergoes a multi-stage process to become the popular nutritional supplement used by athletes and health enthusiasts worldwide.

For every pound of cheese produced, approximately nine pounds of liquid whey are generated as a co-product. This fact leads to the common question: is whey protein a byproduct? The answer is a fascinating look into a product that has undergone a remarkable transformation from waste to wonder.

Lactose, or 'milk sugar,' comprises about 2–8% of the milk of all mammals, making it the only common sugar of animal origin. This crucial milk sugar is produced through two distinct processes: a biological pathway in the mammary glands of mammals and an industrial method that extracts lactose from whey. Understanding how is lactose produced is key to comprehending mammalian lactation and dairy processing.

Whey protein is a high-quality protein derived from milk, and in New Zealand, the story begins with cows that graze on lush, open pastures year-round. This grass-fed sourcing is a core part of what is New Zealand whey protein made of and sets it apart from other types of whey protein on the market. The final product is a testament to the country's stringent dairy standards and commitment to animal welfare.

Over 40% of consumers in 2023 reported purchasing products labeled as “natural,” but the definition can be ambiguous, especially when it comes to supplements like whey protein. The question, 'Is whey a natural protein?' is more nuanced than a simple 'yes' or 'no' and requires understanding its source and manufacturing process to get the full picture.

While both originate from the same cheesemaking byproduct, raw whey powder contains as little as 10-15% protein by dry matter, whereas whey protein concentrate (WPC) is processed to contain a minimum of 70% protein. This significant difference in protein concentration, processing, and macronutrient profile is the key distinction between the two products.
